Just an idea, but if you have enough pieces you can combine your projects and make a mega one.

I have a big one already built (Well compared with the others I've built) But the format that my camera films in doesn't seem to work with WMM. I'm trying to get it fixed.

 this might be a dumb question, but where did u get the balls?

Tom Buckey (author)Nickia942009-10-11

Well for first its not a dumb question.
I get them from sets I got I while back (6-7 Years ago) And you can get them on Ebay. K'nex dont sell the original K'nex any more the only sell KidK'nex and Micro K'nex so the only place you could find them now is Ebay

Go on to buy parts from the warehouse. They have everything.

 ok... thanks

or if you live in holland you can use

bboy18 (author)2010-05-10

I am making this at the moment and wondering why do u need cogs all the way up can i do it with just 2 at top 2 at bottom x

Tom Buckey (author)bboy182010-05-10

Yes you only need 4 cog's but I put more in to make it more stable.

These ball machines you have built are brillant


I just built this and it is brillant
Question: Are we going to see any more ball factories

Videos? Yes
Instructions? No, the reason is beacue the two new videos i will post in 2010 they have already been destoryed to make a newer one which is under construction :)

good luck

flea208 (author)2009-08-27

can you substute the chain for summin else

GeekBeam (author)flea2082009-12-24

you can use mini chain links they work well for me i'm working on a ball machine that features that as a lift. you can also look up ball machine lifts a couple o' guides should come up if you look around a little. i'd go for shadowman39's guide to ball machine lifts it has 13 lifts if i remember right

knexpert#10829476 (author)2009-04-14

Beautiful! One question still lingers, what's so aggressive about it?

smilee (author)2009-04-19

can you substitute the wheels with anything

Tom Buckey (author)smilee2009-04-20

well im not sure youll have to work something out because ive destorryd mine to build my new ball machine. sorry :(

knexpert#10829476 (author)2009-04-16

Those tires come in two sizes. Which size are you using because my ball always misses the ball arm. Can you help?

I believe those are the small ones. (correct me if I'm wrong)

I was using big ones.

they are the small ons :)

knexpert#10829476 (author)2009-04-15

Thanks! I found the problem for the big slide. Not enough diagonal vertical incline or not long enough.

TigerNod (author)2009-04-14

Very impressive, a great improvement compared to relentless! When I have posted my SPARCSS I might just build this!

Tom Buckey (author)TigerNod2009-04-15

cool and thanks !!

smilee (author)2009-04-14
